I remember a discussion > about boot times a few months ago. And why should X start twice? Some of the stuff mentioned in this article is questionable at best. Recompiling a kernel so that the Amiga Filesystem support isn't built isn't going to make things boot any faster than it would if you have it built as a module, as it doesn't get loaded unless it's needed/asked for. Recompiling the kernel to disable selinux/audit is a bit overkill that should have the same net result as booting with selinux=0 Finally, moving ext3 from a module in the initrd to linked-into-kernel code really isn't going to make any noticable difference. The gdm early start stuff is being worked on, so is nothing new. The disabling of various daemons is probably the biggest area where we can see boot-time savings. Some work already happened on this in FC4 (For eg, microcode_ctl should no longer startup if you have a CPU that doesn't support microcode updates). More work is needed in this area for various other daemons/startup code. Dave
